Application alea Jan'uary 9, 1922. serial No. 527,824.

device is to lock this gear Wheel 1 1 against rotation and againstshifting movement lengthwise on the shaft 10 Whenthe gear Wheel 11 isinits neutral position; it being noted that if the gear Wheelll is 'thuslockedfagainst shiftingmovement itcannot v be moved into engagementwithanyV other Vofthe driving gears in the transmission case.

AThe side vWall 12a of lthe transmission case 9 has an aperture 13extending therethrough directly opposite the peripheral face of thegeafrvvheel- 11 when the latter is in .its neutral position lasillustrated. housing 14C for the locking parts of my invention includesa boss or lug 1 5 Which projects into the apcr4- ture 13 f thetransmission case. This housingflflalso has lateral:y flanges .'16 whichare riveted to'theside Wall'12a of the transmission 'case 9" and theseflanges can be reinforced by ribs 175 the rivets being illustrated at18. n* A f j'The housing M includesl a tubular standard 19-v'vhichprojectsupward t'o'such height as to pass through a hole in thefloor 20 of the automobile to which fthe device is l'attachedAnactuatingspindle 211hasa cylin-y dricalgpoirti'on rotatably ritting4Within "the lower portion of the standard 19, and having an enlarged'portion 22 providing a shoulder 51. A transverselyextending slide- Wayis'ormed in thefhousin'gll directly i below theY portion 22 of theactuating spindle vand `Within' this slideWay is positioned a bolt 211.vThisfslidevvayhas an open end25-which extends 'through the boss 1 5` andcommunicates` with the interior of' thetransmiss'ion case. *l The-outerendofv the slidevvay 23` `is preferably closed by fa-'plate 26j`-Whichis desired, can -be brazed or YWeldedsoV asf'to actuallyfform "anintegral part `of 1 the housing 14 land prevent access tothe slidevvay23and bolt 24'; f The' bolt 24 has ai cavity 28 'extendingdo'vvnvvardffrom its'top surface 29; said cavity beingelongatedtransversely. Thelovvei", end` of fthe 'cylindrical' 'portion' 122 r ofthespindle 21 has a yprojection or pinBO of 'cylindrical vform whichtits` in" a ring vor bushing 3 1; the latter being positioned 'Withinthecavity 28'. This; pin or'proje'ction 3()V is ositioned leccentrically tothefaxis of. ro tation of the `spindle 21 -Wthin-thetubular standard 19serba-t it will bencted that Whenthe actuating spindle 2 1. is partiallyrented, rqn1 tbe position shuwn in Fig= tothe spindle by pins 37,.

The bolt 24, at qits inner end, lias"`fteetli at said inner end. Theseteeth or ribs providespaces or notches 34' which are closed at theirsides by portions 35 ot the bolt.`

Thus thespaces or notches 34 are closed at their sides by the `portions35 and closed at their tops andbottoins by the-teeth or ribs 32.. Theseteeth `orrribs are Vof such size that when `the bolt is `moved las abovestated and the gear Wheel 1l is inits neu-tral positionfsaid teeth orribs will `project into the `spaces between the teeth ot theY gear Wheel11 and the portions 35 `ot thebolt will 4be located atioppositevsidesoithelt'eeth of the gear "wheel with Whichthe ribs S2 `mesh s othat when thebolt is in the positionshow'n inv Figures and 6, thejgearwheel cannot be lrotated nor` can it be` slid lengthwise on the shaft.to suchy extent as wouldallow the operation of the automobile uponwhich the devicelis mounted@ As a; means for locking, unlocking androtating the spindle 21, I provide the following 1nechanis1n. l

A sleeve 36 rotatably tits inthe `upper end of the housingstandard 19and `is secured A knob 238 is the `top `end of the standarck Anylwellknown forni of lock, such for example `as affpin lock of the Yaleor-Corbin `type is positioned within the sleeve and has a rotatableportion 39 which, Whenthe lockjis actuatedbythe insertion of a' properkey 40 within la key hole 4l formed in the look Sat the lower end of adepression i. 42 in the.

knob 38, Acan rotateV a cylindrical actuator Y43 which is rotatablymounted in theupper y lend of the spindle 2l. The sleeve 3 6 has holes44 which are opposed to cavities `45` in theactuating portion 43 and thespindle 21` `has holes `46 which `register with i the *.jected after theactuating Vspindle l is ro--v holes 44.` l Metallic balls .47` are Thetubular standard `l9has recesses 48Minto,

which portions of theballsw47 can be prol tated to project the bolt intolocking enga-ge thefba-lls is carried out upon the turning i portion 43by the key independently of the `rotation of the spindle Will cause` theballs Ato be forced out of the cavities 45, inothen Words, from theposition shown in Figure positioned l ivithin `the holes 44 and 46 andcavities 45 when Sto theposition shownin Figure 8. It willufurthernoted" that itliis` action" not only locks the spindle againstrotation within w 1 fthe'tubular standard'but also prevents the or ribs32 spaced "apart inthe directionoti its height. The top and bottonisurfacesof,"` the bolt adjacent said inner end beingbevf eled as shownat B3 sothat the Vbolt tapers spindlev from being lifted'bodily out ofthe Vtubular .l standard.

As'auneans for preventing the upward inoveinenti'ofthe spindle Withinthe hous-l ing when the parts are unlocked, I provide alscreyv 49`Within the housing; saidscrew havinga portion 50 which projects `overthe upperlv surface `51 `of 1t-he enlarged cylindrical portion 22.VFurthevrinoregas a means for preventing accidental rotation of thespindle and also torthe purpose of insuringthat the holes44 are inregistry with the recess 48;.When the deviceis actuated( providespringpressed balls `52 in avt-ransverse passage iinfthe `portion 22.01:the spindle and, these balls innove into recesses `54 in the hous-`ingn` Thus the balls l52 `serve as position Afinders andfcause vthecylinder to stop at the proper `position to allow the balls 47 to bemoved intothe recess`48 and the operator thus knows when to turn thekey.`'Ihetgransi mission casecanbe covered byany suitab'le 1recess ,48.

, i r a In the l usei the device, `Whe-n Yowner or other authorizedlperson leaves` the auto- `inobile,;v the gear Wheel 1l `is inoved intothe neutral posit-lonas shown in Figures `3 and 4by` the movement of theshifting lever and the knob 38 is turned to nieve the 'boltintointermeshing position with the `teetlimof the ngear Wheel as shown inFigures :Sand 6. The key 40 isthen rotated to movethe balls 47. into``therecess'48v and thepkey is rernoved. The gear Wheel 1l`Cannot,"bevrotated and tation.` `Furthermore the gear vvheelll canunotbe shiftedlengthvvise on the shaft 10. While Ihave described myinvention taking la partioi1la'r"form,`it will be understood that thevarious parts of my invention may bechanged Without departing ,fromtheA-lspiritthereof, and henceiI do not limit Inyfselt t to l.the p iprecise construction" set` forth,V `but;consider that Iam at liberty toinake such changes and alterations 'as fairly corne lWithin the scopeoffthe appended claims. l
